Adler k204-370 forward return spring??

Recommended Posts

Normally the reverse lever on the DA 204/205 has enough friction to stay wherever you put it. The DA 204/205 lever mechanism is different from the Juki 441 class that uses a  return spring.

You can adjust the lever friction in two different ways.

1.  There‘s a small set screw inside an outer locking nut directly behind the reverse lever on the backside of the machine. Loosen the outer lock nut and then you can adjust the inner set screw until the friction is „just right“, meaning you can still move the lever and it stays wherever you put it. Small adjustments do the trick.

Don‘t loosen that set screw all the way - it‘ll disconnect from the part it‘s holding and then you have to disassemble a few pieces on the top to get access to put everything back to where it was. The set screw needs to sit in side the notch on the larger clamping part.

 

2. Adjust the clamping screw that is accessible under the lever ( a little tricky to see and get to)

Hopefully the snippet from the parts diagram will help illustrate the parts I‘m talking about.

In my experience both adjustments work fine and I honestly don‘t know which way is „better.“ The screw on the backside of the machine is easier to get to but also more prone to causing problems if loosened too much.
